data-background-opacity image array

[rodrigoalcarazdelaosa]

I know that I can specify an array of images (separated by commas) in the data-background-image field of a section, and also in the data-background-size and data-background-position. But this doesn't seem to be possible in the data-background-opacity field.

Any workaround for this (namely having multiple background images but with different opacity)?

Thank you very much in advance!
