The current integration of Work item types (and maybe other things) between LCS and VSTS is hardcoded, which means that you cannot link LCS to a customized VSTS Template (it is possible, but you're informed that i "May cause errors").

Since the way of using VSTS is very much dependent on how the partner works with implementations and product development (probably different from partner to partner), it should be possible to setup the mapping yourself.

So, the proposed idea is to allow for setting up the mapping instead of it being hardcoded.
