wp-admin over https

Hi.
In my case, wp-admin on all my sites is accessible only over https. But the main sites are http. for example I have a site:

https://www.example.com

but to administer it I use:

https://www.example.com/wp-admin

And on some of them I even have wp-admin renamed.

Can those sites be added in mainwp?
