Anaplan tab in SalesForce user mapping based on email rather than User name

AlainF

We use a different user name between SalesForce (firstname.lastname@company.com.suffix) and Anaplan (firstname.lastname@company.com). Therefore it is not possible to have an Anaplan Tab in SalesForce application matching user names in both applications.

Can you please add the possibility to map between email adresses rather than User names ?

Thank you in advance
