Block-Until-Done could be improved through adding time delay option settings between steps 1,2 and 3. An Excel workbook, for example, must be opened and closed before it can be reread or multiple tabs appended which takes time for a computer to process. Often a workaround or custom macro must be used to account for this time delay. A time delay feature directly in the tool would enable a user to customize the delay period between steps and allow for functions external to Alteryx to complete before next step is taken without macros or workarounds. If no option(s) is selected, default parameters would apply.
