Hello everyone !

I made researchs on google, ended up on this forum, searched here, and I still don't get the answer to my question
So forgive me if it has already been posted, maybe my keywords weren't perfectly chosen (I'm French).

So here is my problem : I am making a website with Xara Designer Pro X, I have 25 pages on the right, and I sometimes have to make changes on one single page.
When I publish, the case "Fast publish (only changed files)" is checked, but yet I can see that all the pages are sent online, and it takes a loooooooooooong time.

I was sure there MUST be a quicker way of publishing only one page, but I can't find it... But I'm starting to think there is not...

Can someone please help me with this ?

Thank you very much !
Nath
