Ability to set default themes and apply themes to multiple analyses Merged

Whilst you can set a theme in a single analysis and copy themes from an existing analysis, there is no way to manage and control custom themes consistently across a set of reporting. To assist this it would be great if one could:

• link dynamically to a theme not saved in the analysis itself, so that a theme can be updated in one place and changes reflected across all analyses using it
• be able to change a theme and apply to multiple analyses automatically, rather than having to open and update each one individually
• define a default custom theme in document options so that all new analyses are created with the same theme

This would enable much easier management of the look and feel of reporting across a large reporting estate. It would also help when migrating reports from old versions of Spotfire as you need to apply a theme to keep a consistent look and feel.
