Question about multiple objects and arrays

[2mik]

Hi,

Please clarify if the following features are currently exist or not:

1. Is it possible to display properties of multiple selected objects to change their properties by a single user action? For example, a user selects Button1 and Button2 to set their properties to the same values. If this feature not supported out of the box, may be you can share an idea how to implement it?
2. Is it possible to add a binding to edit an array?

Thank you.
