Can't Select all or import Image sequences using new Import Screen

I am testing the new import screen and I think it's awesome. The only thing I'm missing is the ability to import image sequences. PNG and TIFF sequences are a very important part of my workflow, it gives me the best quality out of my Blender renders. 

I also saw on this forum response from someone on the team saying that a "Select All" function was added but when I try it on my Windows 10 machine, Ctrl + A doesn't do anything. 

Thank you so much and congrats, you are doing an amazing job guys.
