When creating an allocation schedule, is it possible to use a range of accounts as the source accounts instead of adding each one by one? For an example our source account for a Salaries allocation is accounts 50000-55000. Thoughts we were looking for but can't seem to figure out: Ranges of Accounts - 5xxxxx to 5zzzz Accounting Lists Nodes on a tree (does this concept even exist in NetSuite)

sure, you need to list all source accounts (and combinations of segmentations)

List them one by one under source acccounts?

yes, all of them, one by one

Is there a way to at least duplicate existing allocations?

such as from account A location A to account A location A? yes

No the entire allocation. We have 8 subsidiaries with the same allocation, all that's different is the subsidiary (same source/target accounts, etc.)

yes, any combination of segmentation is possible to include repetitive combination. try in SB, it will make sense then
