The number of allowed activations is set when you generate the product keys. You can either do that in the LimeLM interface. Or you can do it using the LimeLM web API: https://wyday.com/limelm/help/api/limelm.pkey.generate/
If you're already doing it via the web API, then tell whoever set it up for you to modify it so that the number of allowed activations per key is 2 instead of 1.
