When working in MCREATOR, I ran into a problem with a multiblock system in essence

I have a conventionally handlebar seat - 1 standard unit, the procedure is based on detecting 4 wheels on the sides and a block next to it, but it does not move.
How to make it possible to add any number of blocks and lengthen and complicate the machine as in CREATE using glue.
Anyone who can help with this will be grateful)
