You could create a macro which would go through the entire document and apply the spaces after your style. Here is a sample:
Selection.Find.ClearFormatting Selection.Find.Style = ActiveDocument.Styles("DescriptionItem") Selection.Find.Replacement.ClearFormatting With Selection.Find .Text = "" .Replacement.Text = "^& " .Forward = True .Wrap = wdFindContinue .Format = True .MatchCase = False .MatchWholeWord = False .MatchWildcards = False .MatchSoundsLike = False .MatchAllWordForms = False End With Selection.Find.Execute Replace:=wdReplaceAll
You can do the same thing through the Find/Replace function (Ctrl+H)
