You can schedule many weeks at a time and consolidate multiple scheduling requests into one email per person. Load the plans you need to schedule, add people to positions, and send one email with details about all the plans.
Check out this clip from Planning Center University.
Load the matrix with the plans you want to schedule, and then click the dropdown arrow next to a team to expand the positions.
In the team section, there are a couple of different ways you can schedule people in the matrix.
Click and drag the name of the person you wish to schedule to another plan. They will be added to the position, and a notification will be prepared for them.
If you have needed positions, click Needed to schedule a person from the team list. Finalize by clicking the add button.
If you need additional needed positions for the plan, hover over the team name in the header, and click the arrow to choose needed positions. Adjust and save.
Click the icon to send one email with all the scheduled times.
A scheduled person can respond to each individual date by clicking View plan, or they will be taken to Services if they click Respond to Requests.
