Docutain allows you to create addresses you can assign to your documents.
How these are created or changed is explained here:
1. Add a new address
Select “addresses” in the main menu and tap the “plus icon” in the lower right corner.
Complete the mask to create a new address and confirm the data with the “checkmark icon” on the right side of the screen.
Alternatively, you can also import your contacts via the button to the left of the “checkmark icon”.
If you have saved the address, it appears in the overview and can be selected.
2. Edit an address
Tap on “addresses” in the menu. Now you can see all addresses, which are already saved. Then click on the “i icon” or tap and hold the desired address until the option “address info” appears upper right.
Edit the address and save by tapping on the "check mark icon".
