Conditional array build

[falkpl]

For speed of development and ease of reading code I would like to add a contitional array build function.  I use a build inside of a case structure where the true case appends on to the array and the false case does nothing,  why even have the case structure to hide empty code and clutter up the block diagram, the could be easly grouped into a singel function (see below).  I am for anything that cleans up block diagrams and speeds up coding.
