FCToTeXPreviewTermOrder

FCToTeXPreviewTermOrder[exp] displays the output of FCToTeXReorder using the built-in Plus and Times but preserving the original ordering.

Use ReleaseHold or FRH to allow Mathematica return to its original ordering.

Notice that the output of FCToTeXPreviewTermOrder is not suitable for algebraic manipulations but should be understood as an intermediate expression form created to serve as an input for TeXForm
