Custom columns in Document pane?

I use a 3-pane view. In the upper-right pane - the Documents pane - there are columns such as Name, Label, Date Added, etc. If I right-click on one of those columns I get a drop-down list of a few dozen others.

Is there any way I can customize this drop-down list and add custom columns of my own devising?

And is there any way I can make one of these custom columns a drop-down list with pre-programmed choices?

Thanks in advance,

No, adding custom meta data is not yet possible.

Thanks for the quick reply. I’m going to take comfort from the word “yet”, in hopes that a future version will include the ability to use custom meta data.
