How do I replace all occurrences of an object in an event sheet?

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.

Thank you so much!

This is super useful to me.

I know this isn't great project design but it's still a great help to me, because it allows me to take my prototype much further and easily present more and different options.

Thank you!
