IMHDO your best option is as already said ..... tee into crowd plumbing with two 6 way diverters
one diverts from the ram in the default position to the second diverter when energised.
the second one will allow you to select either rotate or clam, which will be operated by your crowd motion on the lever.
the crowd ram will be hydraulically locked where ever you leave it when you activate first diverter.
I'd have the grab action on the default position on the second diverter and rotate on activated.
that way you can set the rotation of the grab to say in line and simply switch back/fore from crowd to grab.

I will look into all ways and hopefully start to learn something too. Thanks again Stuart

diverter valves here Stu

These can be 'ganged' together to cut down on pipework.
6 ports, per valve ..... A & B, C & D, E & F.
Connect your crowd ram pipes to A & B .. and the ram to C & D.
when they're ganged E & F will feed A & B of the second unit when the first unit's solenoid is energised.
the C & D ports of the second unit then get connected to the clam plumbing and E & F ports to the rotate plumbing.
Default in the second unit will give you control of the grab when you energise the first unit's solenoid, diverting the flow from the crowd ram to the second unit and thence to either the grab circuit at default, or to rotate when the second unit's solenoid is energised

job done
Only other thing you will need to do with these is they need a small tank return line to cope with any bleed through on the shuttles, which is a simple 1/4" pipe, tee'd into any zero pressure/open tank return line, or even a line direct into the tank, if you cant'd find a suitable line to tee into.
then all yer need is a couple of buttons to activate the solenoids and a voltage to supply them.
Oh and decide where you want to put the diverter valves. On the dipper reduces pipe runs, otherwise you have to run pipes to the dipper end, from where ever you locate the valves
