Programmatic import in Motoko

Thanks rossberg for a quick answer.
I have x different canisters running with different actor classes. My app should allow to select one of those canisters and create a canister from this actor class. Importing all of the actor classes is not a good option since some of the actor classes will be created after the app creation.

I understand the limitation. I shall try to use the management canister to create the required canisters and load the required wasm from a wasm storage container (which will have to be updated each time there is a new wasm to be added). Is this feasible?
