It would be great to have the ability to draw randomized samples from a large participant panel that could be invited to participate in multiple surveys.

Currently, I would have to assign randomization groups to panel members before uploading them to LimeSurvey and then send invites to randomized groups. However, samples need to maintain the possibility of partial overlap one another, and thus this current method doesn't really work.

Other survey platforms like Kinesis and Qualtrics offer such functionality.
