Yes. You can do this at the beginning of the round and then go back and edit the participants during the round by taping on participants in the menu at the bottom of the screen. Do the following:
Tap on the plus sign on the participant view where you also choose who will be listed as participants in the protocol
2. Tap on Invite to the project
3. Add the information
4. Tap on Save
NOTE! That when you invite a person via the mobile application, for example a responsible person, the person must still accept their invitation and thus you will not be able to assign this person a deviation during the current round. Even if the person accepts immediately, you have already started the round and the app can thus not retrieve the updated information.
