It would be extremely useful to extend the functionality of the App Variables to include the ability to return a value from a Table.
For example, you could configure a “customerfirstname” unique code and have the value return a specific field in a table while you are in that record. This would allow for the creation of user editable templates for things like text messages and e-mails to end users dynamically.
Think “Hi (appvariable), your plumber (appvariable) is on the way. His ETA is (appvariable). Please call us at (appvariable) if you need to make a change or cancel. Thank you! -(appvariable).” would return “Hi John, your plumber Steve is on the way. His ETA is 5:03PM. Please call us at (555) 555-5555 if you need to make a change or cancel. Thank you! -ABC Plumbing”.
Those fields could be exposed in the app as user configurable settings to allow an app user to custom configure those records and the wording. Then use the Twilio Pipe to send the message with the fields dynamically filled.
