Current limited AC voltage source in LTSpice?

Any ideas folks?
So far I've only tried a resistive divider of (say) 10:1 and scaling the source voltage accordingly.
There is a DC version here

Hi, Thanks for the pointer.
I've just quickly scanned and it seems to resolve to a Howland source. Given I don't want to actually make the AC current source physically, I was wondering whether something simpler & neater could be cooked-up in "simulation land".

Hello
the current ''problem'' is first what level of current you want / need as from nA to true full Amp level that not the same at all regarding the involved components

This is simulation only - therefore, hopefully I can choose current at will.
For example 10A, 10V, 10kHz (or whatever). Like a normal "Voltage" part, but with a current limit.
