Search using RegEx, or two consecutive chars with ASCII value between 64 and 91 (A=65, Z=90).

Untested RegEx example:
vPosition = @RegexFindString(ElementName,[A-Z]{2,},0)
If vPosition>0 then you have two or more consecutive UpperCase characters

You may also be able to use @RegexReplaceString to replace the extra UC chars with LC chars.
The search string will probably look something like this: ([A-Z])([A-Z]+)
The replace string will look something like this: $1lower$2
Sorry, but I don't have access to the manuals for correct syntax at this time......
