How to fix AI vectors that use the Illustrator function "Screen"

Hi everyone!
I have a lot of AI vector graphics that I would like to work with in Corel Draw, but when the original file uses the AI function "Screen" it will show like the left dragon below in Corel Draw. Corel Draw doesn't seem to recognize that function and thus doesn't ignore the black. (Same for multiply, as the white areas show.)
Is there any similar function in Corel Draw or another quick way to fix this (without having to redo every single gradient)?

Thanks in advance!
