Make GSA post to subdomains on same domain?

Hi,

I'm trying to make GSA submit to subdomains on the same root domain.

If I use "Allow posting on same site again"

It automatically loads previous URLs.

I only want to post to the URL list once, but the list includes subdomains.

Thanks

Seems I managed to sort of make it work. I just made it 2-2-2 and increased the number per site. Not sure why it was loading the previous URLs before.
