Privates with more than one student MUST be bookable via Parent Portal

We cannot use the private lesson booking tool until privates with more than one student are available. we want to use the private lesson tool excusivley for our dance team. one of the requirements for our team - besides the privates for their solo choreography - is Reformer Training. These are done three at a time. Because we cannot post the Reformer Training schedule to the privates available through the parent portal we cannot use the private scheduling tool at all. The suggested workaround of have parents/dancers call defeats the purpose. We are using SignUpGenius which is a nightmare but it does what we need it to! Please fix this most egregious ommition of functionality. Thanks!
