3-Point Hitch mf135 hydraulic question - back bucket

[GREENBOY]

Hello,
I thought I had found a solution by using a double acting spool working from my MF135 so that I could operate a 3 point attached tipping bucket with hydraulic up and down RAM.
I have just been told/advised that on the MF135 its not possible to have independant movement of the 3 point linkage at the same time as operating the double action spool valve control to move the ram up and down... does this seem right?

this is what i have bought, can it be used on a MF135?

Sorry but u were told right. U cant operate both at the same time.

so does this mean that the bucket is useless on my tractor? or is there a way around it?
