Possible ot use ~~~ instead of ```?

[p91]

Hi,

as a German user, it is very hard to use as a marker for highlighting (I have to press ` four times, then delete one ` to have three in the end. The problem is that just pressing ` once functions as a modifier for the next letter so I get something like this ``à or similar instead ofa).
Is there a option to use e.g. ~~~ instead of the ```?
