Hello,
Yes you can, You can simply create the block under Porto >> Template Builder >> Blocks and then go to Porto >> Page Layout and lets suppose you need to set that block at banner position of the single product page, you have to click on the banner and choose that block, after that set the condition from there as per your requirements, please refer to these screenshots: https://postimg.cc/K4NgpCzp & https://postimg.cc/q6MgdMRb & https://postimg.cc/QKtNy44v
You can set as many conditions as you want from there as per your requirements.
