How to add content to the collection sidebar V2.0 Impulse 5.1.0 (dawn) theme

Hi,

Im trying to add back in the filter by tag functionality into the collection sidebar but there doesnt seem to be anyway to add a new block to the sidebar on the new 2.0 version. Ive made the code but had to put it at the end of the collection-sidebar-filters.liquid code for it to appear in the sidebar. It would be much better if I could do it as a stand alone block as I want to make it more dynamic and it just seems better practice.

Also, currently Ive had to hard code in the tag names to my code which again isnt ideal. I need these to appear as editable options on the customise theme section so that non coding people in our business can change them if nescessary. I can do this part if I can find how to add the block to the sidebar.

Thanks
