Weekly Email Schedule - All trainers - Following week's events

Hi everyone, 

I have a new complex challenge and I wonder if I can get some help here for this integration. Thank you very much in advance!

Context: 

We run trainings/webinars daily around the world. (trainers, calendars, related data)

The logistic is: we schedule these trainings > calendar and > task payment sys (These are all done OK)

The main key data is on Asana, the relevant fields are: 

• Start and finish date/hour
• lead - trainer 
• mod - trainer
• bm - trainer 
• youtubelink
• all other event info

What we want to achieve is as follow: 

Each week - on Thursday - each trainer - Gets sent an email - containing next week’s events in which he/she is scheduled. Events listed on email body

The ideal workflow I can see on Zapier is as follow: 

1. Look next week events (scheduler Thursday 10 am)
2. Look for unique trainers names - emails (on lead - mod - bm fields of each event)
3. Create “key storage data” for each unique trainer name
4. Populate each key data
   1. Search next week events with key/trainer name
   2. populate key event - list all next week events with trainer name on (lead mod bm)
5. run Scheduler - Thursday 10:30 - send email each “Main key data on storage” (trainer name)
   1. Create email body template
      1. Add key data - list all child data into key

Any help is very welcome! Thank you very much!
