Restore form by Document.ExportForm() result

Premium license provides methods Document.ExportForm(). Is there any way to restore form filling by this string? For example if I want to have form filling to be synchronized cross many devices.
EDIT. Look like I can use combintaion of GetAnnotCount and GetAnnot methods. Is there any simplier way or I must stick with this one?

xml form data string are extracted in document level, not page level.
to restore form data string, may need to do much changes.

Yes, but I can go through every page and every annotation in it.

But it look like the only way to synchronize form filling cross several devices. Sending the whole pdf is not a solution cause it may be really large.
