Multi-line string input to workflow

I'm working on integrating with FortiManager via the SOAP plugin to vCO 5.1. One of my steps will be to install/run a multi-line script like this:

# Set FortiAnalyzer
config log fortianalyzer setting
set status enable
set server xxx.xxx.xxx.xxx
set localid FGT60Dxxxxxxx
set upload-option realtime
set reliable enable
end

Ideally, the workflow would take in a text block, assign it to a variable, then insert that appropriately into the SOAP call.

Is this feasible/possible?
