For forms in general (outside of Laserfiche), we are investigating how best to deal with these situations. There are some awkward workaround which work for writing in specific scenarios already, but we do not currently have a general solution that works for all cases. 

For Laserfiche Forms, RPA and Forms will be available on the same server, making it easy to pass information between the two. This specific feature will not be available in the first release, but is something we hope to have fairly soon after. 

If you have a specific use in mind, would you be interested in sharing some details about your use case? If so, then we will keep your use in mind when developing out the more general solution that we hope will hit more scenarios.
