Set multiple components from one hidden field to Jira

[Adrian M]

Currently I have the following to set components:

"components" : [ {"name" : "[entry.component1.escapeJSON]"}, {"name" : "[entry.component2.escapeJSON]"}, {"name" : "[entry.component3.escapeJSON]"}]

This would require me to set multiple fields. One for each component name. 

How can I set multiple component names from one hidden (not user selected) field/array and pass that to Jira?

For example something like:

"components" : [[entry.components.asArray(name)]]
