Hi @Kaudaj,
I just tested it and it's work like charm! (PS 1.7.8).
Did you schedule to have option for select wich products or category you can apply a block ? Goal will be to have a different text depend of category for instance. (see screenshot).
Ie:
Product select:
Block 1 -> id_product1, id_product2 ..
Category select:
Block 2 -> Category 1, Subcategory11, Subcategory12
Brand select .....
Regards,
