Can You Help With applying patches when doing `guix pull` ?

[calcium]

Is there an easy way to applies patches locally (at every pull) without having 
to maintain a whole channel ?

Because I want to have the patch tree-sitter for emacs[1] and the patch 
exwm-emacs-next[2] without creating and maintainging my whole channel !  for 2 
patches that are already compatible with Guix's official channel !! but just 
need a maintainer's approval.

Thanks, it would be very useful (There are lots of patches that I would love to 
have, without the hassle of maintaining a mirror channel with some patches, 
because they can take more than 2 years to be merged into Guix's channel)

Thank you for your help and support.

PS:
I already know about `guix build --patch ...`, but it doesn't do what I want.

Otherwise, would there be a way to create and maintain automatically a local 
channel that just apply those patches ?
