Delivering baseline from one stream to another stream using RTC web client 6.0.5

Accepted answer

In RTC 6.0.5 you cannot create a baseline using the Web UI, and you cannot deliver change sets or baselines to a stream.
In RTC 6.0.6 the ability to create a snapshot on the stream was added to the Web UI (which indirectly makes baselines on components). This was added in: [WebUI] Enable creation of a snapshot from workspace/stream editor. (456128)
In RTC 6.0.6.1 the ability to create a baseline on a component (from within the stream editor) was added to the Web UI. This was added in: [WebUI] Create new baseline (458601)
There is still no way to deliver change sets or baselines in the Web UI.
