Delete multiple subscriptions at once

Is your feature request related to a problem? Please describe it

I want to delete multiple subscriptions at once or delete them all at once.

Describe the solution you'd like

Maybe add some checkboxes to the subscriptions page with an option to select all and delete them?

How will you/everyone benefit from this feature?

I recently sorted out a lot of channels I don't follow anymore and I don't want to edit them in two places so I thought I could just delete them in the app and reimport but there is currently no function to do so.
