Teammate want to share file to my another account in same email.

Here's the problem.

My teammate use B company account shared a file which is for A company,

I own two account in one email, she can't choose which one to shared but only to my B account ( I assume default is shared to same company's account). 

*My teammate only own 1 account.

*I have to switch to B account and download it. Oh no.

---

1. B teammate use B account to share a file and type my email

2. I recieve an email that invited me to edit, but I cannot open because I'm using A account

3. I switch to B account and download it...

4. Sync to A account file by hand...

Question:

1. Is that possible when sharing file we can choose which account to ?  

2. Could I sync two account with same file ?
