Hi @amy1 You can not perform plugin actions in backend workflows as those run on the server while the plugin is on the client. You can use a third party plugin for example to loop through a list of things! Like this one: List Shifter: Reverse, Rotate, Swap and ITERATE (Loop) Over Bubble Lists | Now Part of Floppy
(I think it is now called Floppy)
Hopefully this helps!
