Creating different time slot durations for the same teacher

Scenario: A teacher needs different slot durations for different classes — e.g., 15-minute slots for First Grade, 30-minute slots for Kindergarten. Since she only appears once in the Class Editor, both classes are currently forced to share one slot duration. 
 Solution: List the teacher twice in the Class Editor — once per duration needed — so each listing can have its own slot duration in the Slot Editor. 
 
 Step 1: Add the teacher a second time 
 
 Go to the Class Editor page. 
 Click Add Teacher . This opens the Select Person dialog. 
 Locate and select the teacher's name, then click Select . 
 
 The teacher's name will now appear twice in the Class Editor. 
 
 Step 2: Move one class to the second listing 
 
 Select the second listing of the teacher's name. 
 Select her Kindergarten class, then click Move Class . 
 Select the first listing of the teacher's name as the destination. 
 
 The Kindergarten class is now under the first listing. 
 
 Step 3: Rename each listing for clarity 
 To easily tell the listings apart when creating slots, edit each name — for example: 
 
 First listing: Sue Smith - Kindergarten 
 Second listing: Sue Smith - First Grade 
 
 
 Step 4: Create separate slot durations 
 
 Go to the Slot Editor page. 
 You'll see both listings. Create slots with the appropriate duration for each — e.g., 30 minutes for Kindergarten, 15 minutes for First Grade. 
 
 
 Since both listings are tied to the same underlying contact, the system prevents double-booking — booking a slot on one listing automatically blocks the corresponding time on the other.
