Enforced Predecessor attachTemplate API
Hi All
So I'm looking to add a particular task that I have templated to a significant number of projects, but I need this to have an enforced predecessor.
In the GUI this is an option when attaching a template:

However there is no such option in the attachTemplate action in the "Misc Action" module, only an "options" section where there is zero documentation.....

API explorer doesn't help much either either:

Any idea if this is possible to do via the options string? And more generally where do we find out what the options are for this or any other API calls where this is an argument?
Thanks
