Hi all, in certain situations I want to be able to run a workflow immediately, and then following a specific recursion formula, ie something like  
“R1 & R/+P5D/P7D” but this does not validate. What is the correct way to implement this?  
Thanx and cheers!

So close, it’s: `R1, R/+P5D/P7D`.

A few other Cylc configurations support using commas to define multiple items in this way, e.g:

```auto
[runtime]
  [[foo, bar]]
    script = true

```

Aha, I didn’t think of trying that! Thanx @oliver.sanders
