I do use lot of custom data to manage payment, payment date and so on
Would like to setup thing differently and have the possibility to customize thing the way that suits my need.
You can see some inconstant date format from “modified date” dd/mm/yyyy HH:mm and custom data which is far too long dd mmmmmmm yyyy (fortunzely we can remove time but it is not enought)
At this time, don’t use a Date data type. Use Single-Line Text and you can construct the format you want. You can even use placeholders for this.
