Is it possible to upload more than 1 file at a time?

Also a side question – is there any upload limit defined within the Client Document Manager files or is that purely determined by the php.ini in the main directory of my website? I’m attempting to upload a 250mb file but after a while it just seems to go to a blank white page (i’m guessing once it’s reached it’s 100mb limit which seems to be imposed). 
I’ve managed to change this with my host so I now have a 300mb upload limit but i’m still unable to upload the file within the manager.

Hello, with premium you can upload multiple files at once, it also uses file chunking and uploads files in 1mb increments so there are no upload limits
