I have just (for only the second time) used the Edit Rules screen in the Modern interface; I have been converting the filtering rules of my Guest account (which closes in about two weeks) so that any matching mail, as well as being sorted into the matching folder as before, will also be forwarded to a corresponding folder on my Basic (formerly Member) account.

This of course entailed adding another rule, such that all mail which doesn't match the other rules gets forwarded to the robertbak.inbox folder anyway. That rule appeared at the start of the list, making the other rules redundant; but when I went into Edit Sieve to correct this, I found that it had actually been created at the end of the list as intended, so it should work correctly.

I hope this setup works...
