We would like to create an application where a user can select a topic and the relevant markers will be trackable after the topic has been selected.
Each topic will have between 10 to 100 markers.

I modified the image targets app (in iOS) and added a config file with 10 markers and the app works as expected.

My question is how can I load in a different config file?
I understand that QCAR looks for the config and data file in one place so my idea was to have a mini utility that runs and replaces the contents of the config and data file at runtime with ones selected as a result of topic selection. It doesnt matter if QCAR has to reinitialize because we will simply put a relevant loading screen.

Is this feasible? Are there simpler ways to do it?
