Quartz.Net - delay a simple trigger to start

Question

I have a few jobs setup in Quartz to run at set intervals. The problem is though that when the service starts it tries to start all the jobs at once... is there a way to add a delay to each job using the .xml config?

Here are 2 job trigger examples:

 <simple>
    <name>ProductSaleInTrigger</name>
    <group>Jobs</group>
    <description>Triggers the ProductSaleIn job</description>
    <misfire-instruction>SmartPolicy</misfire-instruction>
    <volatile>false</volatile>
    <job-name>ProductSaleIn</job-name>
    <job-group>Jobs</job-group>
    <repeat-count>RepeatIndefinitely</repeat-count>
    <repeat-interval>86400000</repeat-interval>        
  </simple>

 <simple>
    <name>CustomersOutTrigger</name>
    <group>Jobs</group>
    <description>Triggers the CustomersOut job</description>
    <misfire-instruction>SmartPolicy</misfire-instruction>
    <volatile>false</volatile>
    <job-name>CustomersOut</job-name>
    <job-group>Jobs</job-group>
    <repeat-count>RepeatIndefinitely</repeat-count>
    <repeat-interval>43200000</repeat-interval> 
  </simple>

As you see there are 2 triggers, the first repeats every day, the next repeats twice a day.

My issue is that I want either the first or second job to start a few minutes after the other... (because they are both in the end, accessing the same API and I don't want to overload the request)

Is there a repeat-delay or priority property? I can't find any documentation saying so..
