How to handle side-nav with multiple items?

I have built a dashboard where the user can handle totals for all it's shops, in a side-navbar over the items like 'settings', 'exit' and refs to other pages there are all shops listed as tree view, you can open a shop and select the cash-point of which show the data or just deselect a whole shop if you won't see it's data, i think the user must be able to keep an eye on the shops he selected choose to see the data so i decided to place them inside the side-navbar..

There were no issues and it's looked good till i set the dashboard for a client with a lot of shops... and it's horrible... as the shops are listed before the refs to other pages the user just can't see them and have to scroll the navbar...

So i was wondering on how can i manage the way to let the user keep an eye on shops but till not make that nav-bar look so horrible and confusional..

Should i just put the refs to other pages before listed shops?

Anyway here is how the nav-bar looks like
