Dynamic tags in Table

For an Easy Chart, pens can be dynamically changed because the "Tag Pens" property is exposed and bindable. This allows custom trend screens to be created (as seen with Ignition's ClickToGraph goodie example download).
Although the Easy Chart can display dynamic data, it does not expose an output property to present the gathered data in a Dataset.
Suppose a user would like to view data in tabular format instead of a graph...
I've noticed that tags can be bounded to a "Table" or "Power Table", but these are not dynamic.
Request:
- Expose a bindable Dataset property in the "Table" and "Power Table" objects that allows the selection of tags to be dynamically populated in the table.
- Expose a Dataset property in the "Easy Chart" so that the data can be used by an external object. (It doesn't make sense to query the same tag history twice, once in an Easy Chart and another time for a Table)

You're right. These are 2 requests. Please treat as separate requests (not ether-or, not cumulative)
Request 1 reworded:
- Expose a bindable Dataset property in the "Table" and "Power Table" objects that would be analogous to the "Tag Pens" property in an Easy Chart. When a developer writes to the property, it would be the same as if a developer editing the Data property binding in the Designer and hand-picking tags for "Tag History" binding type. Same thing, but dynamic.
Request 2:
Yes, extension functions would be perfect. One to get # of datasets. Another to get dataset by #.
