Numeric custom fields

[ACE]

I'm trying to reduce manual work on cards.

I've discovered I can create actions that use numeric values ​​from number-type custom fields.

Now I'd like to know if it's possible to do two things.

1. Can I set up an action (or button) where a numeric custom field adds up specific values ​​(such as "€20") indicated in the card description?

2. Can I fill a numeric custom field from a comment? For example: "Cash Deliver €5" and have the field filled with the value 5.

Other related tips are welcome.

Thanks.

(1) not that I know of. The only arithmetic of any kind is for date

(2) it should work using wildcard like “Cash Deliver €{*}”  when you add it to the card description.
