Using the email address of the user to identify the programs the user has applied/enrolled for.

**Is your feature request related to a problem? Please describe.**
Since this application would be used by an organization, would it be possible to use the user's email address to identify the programs the user has already applied or registered for? Then the user need not go through the program application process through BIT and could directly view the mentors or mentees under those programs.

**Describe the solution you'd like**
this feature maybe related to https://github.com/anitab-org/bridge-in-tech-backend/issues/153

**Outcome**
The deliverable for this issue would be an md5 file with screenshots and documentation on how this can be implemented in the backend.
