@agczsz Welcome to the forum!
Your suggestion seems to be a variation of what was previously proposed in the Feature Request thread “If only Default collection exists, pre-fill it as checked”. Do you mind if I merge your request with that one, or would you prefer for your proposal to remain as a separate request?
If the requests are merged, you could edit your post to further clarify that your suggestion is an extension of the previous proposal, by allowing for the Default Organization to be pre-selected under additional conditions.
