Cant drag and drop into layers in standalone GA5

I’m trying to load several samples into one pad in a standalone GA5.

When i drag and drop a sample into GA5 from the media browser when its loaded into cubase i get 3 options apear on the pad when i hover over the pad. But when i’m in standalone version there is only the option to replace the current sample when dragging from the inbuilt browser.

How do i load more than one sample into a pad in standalone GA5?

This is in win 10 20H2.
