Enable/disable automatic Images Download per gallery

Hi! I am using your wonderful plugin for a client and he would like to have the option to enable the automatic Images Download per gallery instead of having one setting for all galleries. For example:

For a customer he would like to enable the automatic images download on a specific gallery. The customer can then select the images he/she wants and then download the automatic created zip-file.

However for a different customer he would like to disable this option on a different gallery and only wants the customer to be able to select the images he/she wants and no option for download. So basically he wants to be able to activate or deactivate the automatic option of downloading images per gallery.

Is this possible in any way? Or could this option be requested as a feature?

With kind regards and thank you for your help,

Ilse
