Subitem duplication

Hi there

Is there any plans to allow a set number of sub items ( of repeat nature ) to be added to multiple pulses at once.

Example:
Sub item list:
Screws
Hinges
Door
Frame
Lock
Latch

300 pulses of a unique door now require this sub item list to be copied , same list but different doors in different location , at present you would have to duplicate and move 299 times and some of schedules are 3500 which would not be feasible especially if you forget something it would need to be copied again and moved another 299 times

Hope it makes sense
