Block Visible Only To User Groups

I would like to know if it is possible to have some blocks only visible to members of certain user groups. For example, I have some wholesale customers who are members of a wholesale user group. I would like to have a product tab on my product listing page which is only visible to members of this group.



I would appreciate it if anyone knows how this can be done and they share the information.

There is no much option left in blocks for different user types. to my knowledge.



but still you can show different price for retail and wholesale buyers.

you can have categories only visible to certain user groups then assign the block to that category, but may cause you problems having to create duplicate categories for customers.
