highlight Begin / End

Please let me know if this capability exists already, but it would be great if SQL Prompt could highlight begin/end pairs similar to how it's done in SQL Assistant. I suppose if SSMS included a feature that defined collapseable/expandable blocks of code like most code editors the issue would be less important, but in a stored procedure of any length, tracking blocks of code (IF statements, WHILE blocks, Begin Try/End Try, Begin/End) really improves productivity and reduces errors
