Ability to output to the same Excel file more than once on the same workflow

[gabrielvilella]

Currently, if the same Excel file is being updated on the workflow, but different sheets within the file, it will error out if the saving process overlaps one another. And there are some cases that using the tool Block Until Done will not work because there are two data streams (for example if you have a filter and is saving the data from the two outputs on the same file).

It would be great if we could output to the same Excel file more than once on the same workflow.
