Bags and Inventory

So I do some meta map events like quite a few people in gw2. I hate at the end when i go to sort through my bags and then discover my invisible bags are filled with random crap, so it got me to thinking and i haven't found an answer to this question so i thought i would come on here and ask:

Is there a way to lock bags so nothing goes into them unless you personally move something into them?

I know they want us to buy more bag xpacs and bank tabs and crap but i still dont think this would kill them to much for this to exist if it doesn't already, but does anyone know?

No there is not the only way to avoid filling invis bags is to have the filled before you start picking up loot.

Would love to see this functionality for bank tabs also, but currently there is no way to do that.I've taken to either using smaller invisible bags, filling empty invisible bag slots with useful items, or just working around the inconvenience.

I sometimes get something from the crafting storage and split it up, to fill up invisible slotsit's easy to recombine or deposit to make room if needed

The nearest you can get to this is to make sure your invisible bags are always at the bottom of the list, that way they won't fill up with random stuff unless every other slot in your inventory is already full. If you open a lot of champion bags you may still need to check for random items in there, but it will be a lot rarer.

Personally, I keep my Invisible bag at the top, but holding a couple things that don't actually need to be in one, so there's room to switch with drops I want to keep safe. This used to be gathering tools before I got permas, but now it's things like the Birthday Blaster and the Exalted Portal Stone.
