How to update multiple sites in one repository on bitbucket pages?

Question

Bitbucket

Hey!
I want to use Bitbucket as hosting for static pages (repositories are private).
To do this, they suggest creating a repository called accountname .bitbucket.org, which will be the address.
But I don't want to upload sites directly to the root, or create several accounts, but have access to them at
http:// accountname .bitbucket.org/ project1 ,
http:// accountname .bitbucket.org/ project2 .
On the local machine, I have separate repositories project1 and project2, and accountname.bitbucket.org .
How can I edit several sites separately (project1/2 repositories) and push these changes to the corresponding subdirectories of another repository without unnecessary movements?
PS I tried to make a submodule from project1/2 in the accountname.bitbucket.org repository, but bitbucket does not accept it.
in general, just copying it works .. but this is not the case ..

Answer 1

GitHub Pages support submodule ( proof ), so maybe host on ghab?
