Localized or customizable Keyboard shortcuts on iPad

I live in Switzerland and use Magic Keyboard with a Swiss layout, which differs from the US layout in several ways. This usually results in less accessible key combinations.
Some of Agenda‘s keyboard shortcuts that I would love to use more are quite tricky. For example, increasing text size (‚command‘ + ‚!‘) requires me to press

command + shift + ¨ (which becomes ! with active shift)

I suppose for US-keyboards (and maybe others), the requirement to press shift to get ‚!‘ falls away, making this shortcut significantly easier to use.

Is there a way to solve this issue, or is it a restriction of the iPad?.

Best to check again once Agenda 14 is out, it has some changes to how menu shortcuts work that might solve this.
