If you have multiple attorneys at the firm who can sign a document, you can create conditional fields to auto-populate the selected attorney's information:
Step 1: Create a single-select field with the attorneys' names
Step 2: Create a conditional field for each attorney to pull their corresponding information ( e.g. bar number, phone number, address)
At the time of drafting you just need to select the attorney, and all corresponding data will auto-populate in the template!
