Type parameter to control built in parameter Possible?

[Anonymous]

Is it possible to use the share/type parameter to control the value of the built in parameter?

For example if I have a Yes/No parameter to check the Start/End connection, the Start/End Connection option for moment frame will be also got automatically selected/deselected. I was thinking there are some kinds of codes that I can put into the formula the access the built in parameter data, but looks like it doesn’t woke that way. 

This question maybe out of topic in this forum because it might not be API related

But I can’t think of any another place to post this idea.Thanks for reading

UI may not support this.

the only way in API now I can think of is using dynamic model update API:

the idea is: hooking a paramete change event and in the event handler , you can do whatever you want, e.g. change another parameter in your case.

but it is a little complicated.
