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

We currently provide a single config param to set the max cache folder size per signal for every signal here. It doesn't allow to set a different size depending on the signal type, so we should make it possible.

This issue was initially raised here.

Describe the solution you'd like

Add getters per signal in the config file.
