This setting allows us to select various php formating functions for our View Tags:
Fields->View Tag->Format
The help guide explains that we can also use our own Custom function for String formats:
Fields->View Tag->Format->String->String function->my_global_php_function({value}, time(), $whatever)
If I am using my_global_php_function on many fields, it would be very handy if I could have it populate in the dropdown with all of the inbuilt String functions.
Q. Is it possible to somehow append our own global functions to the String format dropdown?
[I know we could make a Custom View Tag and use the Custom View Tag dropdown instead, but still interested in seeing if above is possible].
