Importing all images at once from bulk import

I wanna be able to quickly just select all images then import them into roblox studio workspace:

select all images with mouse and drag it into the display roblox studio

no, im making a animated skybox plugin it has to be like ctrl + a (in windows to select all files) but roblox dosent have that

i see
click to the import button
and press ctrl and select all your image files in the opened dialog

i dont mean that, i meant just using keys that select all the files for u, u cant do that since there will be 1000+ images
