I think the title sums it up but here's a slightly more detailed framing of the question:
I have an event sheet that is working as intended but I want to make more levels and each level should use different sets of sprite objects.
I would like to copy event sheet 1 to make event sheet 2. In event sheet 2, I would like to replace all occurrences of sprite_1 with e.g. sprite_7.
Is this possible?
I only know how to replace objects one occurrence at a time.
