Delay resource assignment

Hello PPlanners and SP users,

I cannot find how to make a resource to start later than the activity start date;

for example, Activity A is 2 week long, Resource 1 will work 10 days, Resource 2 will only work the last 3 days;

Resource 1 and Resource 2 are part of Team 1 and Team 2 respectively; 

I do not want to split my activity into A and B with a FF link

Thank you for your help,

Alexandre
