Proficiency Testing for different ACT cartridge types

For those of you who perform both ACT-LR and ACT+ testing on a single testing platform, do you do proficiency testing on both cartridge types?  We use the Gem Hemochron 100 instrument and began with only the ACT-LR cartridges, and did proficiency testing on these.  Now the providers have requested to add ACT+ cartridges for our EP Lab and we are ready to go live with these additional cartridges now.  I was thinking I would need to subscribe to another proficiency testing program for these ACT+ cartridges, but not sure since they both are technically ACT testing if that would be necessary.  We are a CAP accredited facility.  I did submit a question to CAP, but while awaiting their response I figured I would see what other facilities are doing in regards to this.  My email is aholland@catawbavalleymc.org if you would prefer to respond via email.  Thanks!
