Run flow ONCE when any (or all) items is a SP list is created or modified

[ZedYer]

Using a SP List as a data entry form which can contain 100's of rows to process. 

1_ User pastes the entire set of data into an empty SP list.  Triggers flow.

2_ Flow processes data, routes to other process owners.

3_ Flow deletes all records in the SP list for next user.

Is there not any trigger that will trigger based on either a create or modify of any item in the WHOLE list and not on each ITEM in the list?  From my research, it seems I have to set a trigger condition and add another "status" column, which I can do, although it seems that this would be a common enough 'feature' that maybe it was already solved in some way.

Thanks!!

I think I solved this myself:

Trigger: When an item is created or modified.

Settings: Not clear, but "Split On" toggle is on the left side which seems to mean it is "On" but the Array section is grayed out so it appears to be off.  Either way, this worked.
