Hi!
Sure, yes. I’d want to organise my records based on three group tags, “DocType” (could be ad, receipt, bill, etc), “Source” (essentially whom created the document) and “Regarding”. Only the group tag “Regarding” can contain several tags for each record:
I try to follow a nomenclature when adding documents which is YYYY-MM-DD - DocType, Source, Regarding. This is important to me. The tags are also added correspondingly. Since this to some order is automated using Hazel, some work also needs to be done manually. This is what I want to avoid using the AI of DTP3. I hope to get an easier way automating stuff to OmniFocus, have an easier time finding and culling my documents.
What I want to accomplish is for DTP3 to look at the document contents and suggest a file name, rename the file and add the tags. This would be based on the found records using the compare function.
I’d like for DTP3 to suggest not any tags, but the relevant child tags. I.e. when the new record is matched against documents, I’d want the suggestion for the DocType to come from the child tags of the group tag “DocType”, not the group tags “Regarding” or “Source”. Ideally, for a new record containing a receipt, I hope for one of the suggestions of the “DocType”-tag to be receipt.
For this, I’ve built a handler which find group tags (using capital characters, other tags don’t), findTheTagNames. The handler returns a list of the name of the group tags.
Further, I’ve built a handler which returns a list of tags which are children of the given group tag name.
Hope this makes sense 
Regards,
Björn
– 2019-06-27: Updated, trying to create handler for finding child tags. During testing, I cannot get the name out of the tag (at least what I think is the tag). Posted question on how to do this in the DTP forum.

– For finding tag names of a record, based on how the tags of the record is set up. This is useful if the tags are already children of parent tags. E.g. if the record contains the tag “kvitto”, and the tag kvitto is a child of the tag “DocType”, the tag kvitto will be the result of the handler. Handler has to be created, though. This can be used in conjunction with the DTPO test 4 script that is used to compare a given record and suggest tags based on other records in the database. In the case of matching, instead of suggesting any kind of tags of the matched records, using this sketch, tags for e.g. DocType could be suggested instead.
