Explore adding conditions to price list items

I was looking for this functionality as well.
We have a website that has pricelists 'linked' to a value on the user entity.

We import our pricelists from an ERP, and we've worked around this issue by hooking onto the user & pricelist insert/update events.

Pricelist on insert/update:
- Find all users with the custom value and attach them to the customers field
User on insert/update:
- Remove the user from pricelist(s) with the old value (if applicable) and add to pricelist(s) with the new value

The main problem here is that, if no users have the value of that pricelist, the pricelist applies to EVERY user. That's something that conditions would have easily solved.
In our use case, we've solved this by creating a 'dummy' user and if no other users apply for the pricelist, we attach the 'dummy' user to the pricelist.

Configuration/development wise this would have been much faster and cleaner if we had conditions, but I understand the argument of speed is a factor here too.
I'll set this as postponed, it's not and hasn't been really an active issue and if the need arises later on it can be reopened.
