Uploading vids from camera roll

I’m very pleased with the new update, very well done! One thing i’ve noticed is now we’re only allowed to upload one video from the camera roll to the byte camera despite the length of the video. For example if I upload a 3 second clip Byte won’t allow me to add on to it through the Byte camera nor upload another 3 second video on top of it… Is this permanent? For the time being i’m using a video editor but I miss the easier way of doing it through byte!!
