In the Quarto project profiles documentation, when we have two environment files named _quarto-advanced.yml and _quarto-production.yml, we gain the capability to render a document under either a single profile or multiple profiles using the following commands:

# Render a single profile via command line
quarto render --profile advanced

# Render with multiple profiles via command line
quarto render --profile advanced,production

The functionality for rendering with multiple profiles relies on one of the profiles specifying an output-dir: value that differs from the current working directory.

In light of this, could we consider enhancing the Render button's functionality to allow users to either render all available profiles or select from a list of profiles, similar to the options for rendering to PDF, HTML, Word, and other formats in R Markdown, as shown in the example below:

Furthermore, is it feasible to extend this capability to Quarto extensions, enabling them to automatically specify and run different profiles together? This would streamline the process for users, eliminating the need to manually issue the quarto render commands mentioned above.
