My income varies from month to month. What I would like to do is, every month I would like anything over a certain fixed amount to be transferred to savings pot, is this possible?
No. The closest thing is salary sorter.
When you get paid, it allows you to set a fixed amount to go into various pots. Then next time you’re paid, it remembers this and you can just confirm to do the same again.
If your pay is varied, you can keep all your “regular” pot deposits the same and simply adjust the savings pot amount.
