Thanks for your post.
In answer to your questions, E-Docs functionality was released as a priority to help facilitate as much of a contactless workflow as possible.
This was an evolution of our E-Sign feature, hence the current limitations, but yes, we are planning on adding to this, and we will continue to improve it on into the future. We just wanted to get that core functionality out there as soon as possible.
In the meantime, is there any way you could split the long document down into individual forms? Perhaps 3 forms breaking it down into 10 minute sections?
That way, when a patient clicks next to go onto the next form/section, this is automatically saved. If the patient comes back to it later, the section they have already submitted will remain saved.
