Feature request: Add possibility to add icons to custom subsetting in bulk

[ruimendes29]

Is your feature request related to a problem?

Currently, we use custom subsetting in our project, but to manage it, we needed to create a rather hacky script that goes through a list of icons we use in our app and adds them to the kit. It would be nice to have some way to directly provide Font Awesome with a list of icons instead of having to add each of them manually

Feature description

Either a command that we can call with the list of icons as argument or someway to do bulk changes in the UI directly
