Setting default options for (all) reports

[tass]

Hello,

Is there a way to change globally the default value of the report options? (and man do I hope the answer is yes)
Setting the "group repeating cells - export to excel" to no is the intent, both for existing reports and new ones.

Similarly, I am looking for a way to change the default portal action for the reports (from view most recent to run).

(Not sure if this goes under administration or here)
