"System / Send Intent" action should support list-valued EXTRAs

I want to launch an app (http://kaljurand.github.io/K6nele/) that supports list-valued EXTRAs via Tasker, but Tasker's "System / Send Intent" does not seem to support such EXTRAs. This is what is supported according to http://tasker.dinglisch.net/userguide/en/intents.html

If the value can be parsed as an integer, long (integer ending in L), floating point number, double (float ending in D) or boolean (true/false) it will be treated as one.

The value can also be forced to a simple type (long etc) or Uri via casting.

The name of a Java object created via the Java Function action which is of type Parcelable can also be used (e.g. a Bundle)

If none of the above apply, the value will be treated as a String.
