Suggestion for WBS Default Value Prefill?

When wanting to add take off when using a sort sequence that has many levels, let's say 4, you select the Default Values feature, and then for each of the four values, you select the appropriate WBS, each one, four times.

Since the "Prefill" concept of saving time is already in Sage, can we have a "Prefill" button that would, for each WBS in the sequence that is either set Takeoff or Detail, insert the values based on the current record? Seems like a time saver for those of use who have multiple WBS estimates.

Example:

I am reviewing an estimate and I need to add an assembly in a section of the estimate spreadsheet that already contains items.  I navigate to any cell in that area, select Default Values, select Prefill, and the WBS values of the current record, namely, Area, Bid Item, System, Floor, and Drawing, are inserted into the Default values.  I then go to Assembly takeoff.

Thanks for considering ....
