No. (Yes, but over here: Alternate solvent extraction)
Suggesting using the compressor already on most cls (recovery pump) to move gas (N2 or air).
Using said gas to move lipid around, and agitate reactor during decarb.
Aka running “oil” in an unmodified oil rig (ok, modified to blow hot smoke up its ass, but they should all have that functionality)
Which was the topic until you switched to using a stirred pot… 
Yep, I had that functionally (same solvent serially over multiple columns) for about a week. It’s not a hard add to most multi-column rigs. It IS pretty hard for the operator to keep track of in my experience.
You’d need an extra honey pot or three to effect said counter current methodology on most single column rigs
