A way to batch change Loop Options in Frame Picker?

[vancorbo]

I sometimes get absent minded when building an animated symbol with lots of parented symbols within it and forget to set them to "Single Frame" before moving on (My Animate has always defaulted to "Loop")
I only realize this later when I notice my symbols strobing through all their keyframes and have to go back and change the Looping Options for each keyframe individually—as selecting multiple keyframes greys out the Looping Options.
Is there a way to select multiple frames and change the Looping Options in one fell swoop?

OR

is there a way to change the default Looping Option to "Single Frame' so I don't have to worry about it?

It is possible to change the looping of multiple keyframes at a time by using the "Edit Multiple Frames" button.

Select a range then go to the properties to change the loop setting.

I had tried this before posting and found that the Loop Settings were also greyed out

I see now. There is a separate section in properties for looping, and that gives me the result I needed.
Many thanks!

Seems to be a bit of conflict between the "Looping" properties and the "Looping Options" in the Frame picker.
They do the same thing, do they not? But one is accessible and one is not.

Oh well—I've got what I need. 
Thank you again.
