Hide all mappings that do not have a description.

[blasco]

Hi, first of all thank you for such an amazing plugin!
I've seen that there is way to hide mappings:

let g:which_key_map.1 = 'which_key_ignore'

But is there a way to simply hide all mappings that do not have a proper description?

My current setup is not very useful:

I would like to show only the commands that I've written a description for. Does this make sense or is there a better approach?

Or is the only solution to write the 'which_key_ignore' for each single mapping
