Additional function required in Requests for bid business process

Hi,

I kindly request additional function as an udesigner set for Requests for bid BP.
I hope function described below can be adopted and applied in upcoming version of Unifier.

a. uuu_rfb_due_date
- due date can be modified after bid invitation. this is the problem our customer issued.
- best way to it, Option should be added for "Allow modification of due date after bid
invitation" and "due date cannot be modifed after bid invitation" in setting of the BP

b. Excel template column arrangement
- If bid items are more than 100, most of bidders update the bid items through Excel import function. However, Excel columns are jumbled up and the udesigner cannot sort the order of columns in Excel templates.
