Append to Existing- Prepend?

[AmberSJones]

Currently, saving using the append to existing option assumes that data are only being appended to the end of a data series. However, what about the option of prepending data to the beginning of an existing data series? Do we want to support that option? If not, should we add a warning that data may be lost.

per our meeting: add a line of text next to append "Add values to the end of a series"

@AmberSJones ready for testing on branch appendtext

[AmberSJones]

Great- just needs some minor adjustments. Should read: Append to Series (adds values to the end of a series)

@AmberSJones ready to test again

[AmberSJones]

Great.
