Siblings, Uploads and Cost

I have some concerns I'd like to share as the Director of Early Childhood for a public school district in Michigan:

Uploads: I did an hour-long support phone call a couple weeks ago before purchasing, and was reassured parents could upload documents onto myprocare.com. We are not using the engagement application as we already have one, which the support person knew. Now that I have purchased, we found out parents cannot upload.
Siblings: We need a work-around for existing/returning families who are registering a new sibling. There should be a way for them to add a new child onto their existing account. We are a large center and have siblings enroll all the time. Part of our reason for paying for ProCare cloud was for parents to do these tasks themselves, not have us still do them.
Cost: I was offered the ProCare cloud for $49/month if we used the payment services, which I am not allowed to use as part of a school district. There should be an exemption for public schools. Now I am paying $130/month to use less of the product (as I cannot use either the payment system or the engagement app, as part of our state-funded preschool is required to use a different system.) So we are getting punished essentially for factors outside of our control.
