Thanks for replying – I actually didn’t notice that someone did reply :).
If I understand what you are saying correctly, I can pass arguments to add_custom_background to change what it modifies, but I can’t pass any arguments to it so that it will modify more than one element – is that correct?
If so, then perhaps I could modify the add_custom_background function to accomplish what I want – i.e., to create a multi_add_custom_background function? My only question would be on how to actually do that – any ideas?
Thanks and be well,
Moshe
