A partner has raised a limitation of our product being the CRM Business Central integration only taking a single company into consideration without the option to choose which company that would be if there are two or more available in the Business Central environment.

An idea from 2018 goes over the scenario and there is positive feedback, however, the functionality has not been implemented since:

I believe it would be great improvement of our product if our partners and customers are able to choose either one or multiple companies which are to be connected to CRM, if more than one is present in Business Central.
