Possible to add item to a running queue from CLI?

[SamKook]

I have a bat file that creates a queue file and then launch flashfxp to upload the files.

But since my upload speed is pretty slow, I sometimes need to add items to a queue that's currently uploading and I was wondering if it was possible.

From what I can tell, there's no way of doing this(automatically) other than starting another instance of flashfxp, but that will slow down my upload too much and it will timeout and fail even more than it already does.
