KB13466: How to set defaults to different objects and editors in MicroStrategy Developer 10.x

Some users would like to set default values and properties for different objects and editors in Strategy Desktop.
 
Common questions:

1. How do I set the row and column widths on grids to a default value before a report is created?
2. How do I set the Dynamic Aggregation function to SUM as default for a metric?
3. How do I set a default Auto Style for grids on Report Services documents?

A solution to many such questions is to create templates with the desired properties and values and place them in the Object templates folder.
