Is there a way to randomize blocks but keep constant blocks within the randomization?

Hello,

First time poster so forgive me if I'm not asking this correctly...
I'm making a survey in which I want participants to see 12 randomized blocks. As they're going through the survey I want them to be able to keep track of how many blocks they've gone through (in addition to the progress bar). There's a lot of content they have to go through, so I'm hoping that telling them that they'll go through 12 and letting them know which number they're on will help keep them oriented.

Is there a way set it up so that I'll have constant blocks telling them their progress within the actual content blocks that are randomized? Something like: "You're on block 1" > see one of the randomized 12 blocks > "You're on block 2" > see the second randomized block of 12 > "You're on block 3" > etc.

There are 12 randomized blocks and I want them to evenly see all 12. So the blocks keeping track of the block number they're on will stay constant but the block they see next (with the actual survey content) will always be randomized. Hoping this makes sense. Any help is largely appreciated!
