I do know a way to do a quick check for them.... you could make a check that would open the packs if the bandage isn't found....
The command to find something is
finditem. It looks complicated but it's not.
To find something ANYWHERE on screen
finditem %something
To find something on the ground within 3 tiles of your char:
finditem %something G_2
To find something in your backpack:
finditem %something C_ , #backpackID
To find something in another container
finditem %something C_ , %bag_to_keep_open_1
There are a couple ways you could check your bags... or you could just keep them in your backpack and use "event macro 8 7" right before using a bandages in CEO medic to ensure your backpack is opened.
