Hello JSmith,
Thank-you for your question.
It is true previous versions of the ZPX (Zap-fix) v14 we did not have this method, but in our new upcoming release (ZAP-fiX 14.0.23 BETA) this method will be there.
Please note that ZPX is fully customized utility, meaning, because we develop ZPX we can update it to any Client’s needs (Even a specific needs only for a particular Client orand application);
Therefore if you need other adjustments, updates, adding new features just for your need, please do not hesitate contacting Zap and we’ll do our best to send you the customized version just for your needs.
Please contact Zap for further help.
Thanks,
Sasha
