Document generation field link id's

Seems when you retreive the links for inserting into doc, the link becomes the original name, when you create copies of a field many times
Example. Original field called = "Engine Oil"
when you copy the field because by default new field becomes
"Engine Oil copy"

next copy becomes
"Engine Oil Copy Copy" and so on.

even If i chance all the names details to a new field, the Link uses original name generated and not the amended field name, so there is now no easy way to identify the links are correct.

Please address this short fall, by allow us to set the link naming in the form designer if required.
