How to enter macaroni on spreadsheet?

When the text to be sung mixes languages (beyond what we are accustomed to have in our hymnals of Hebrew [hallelujah/alleluia, hosanna, Abba, amen...], Greek [Kyrie eleison, Christe eleison...], and Latin [Gloria, in excelsis Deo, Salve Regina...]) how should the language(s) be entered on the spreadsheet?

I'm thinking in particular of Brian Wren's English versification of a Muscogee (Creek) hymn that begins

Heleluyan we are singing Hele, Heleluyan...

and of well-known carols, occasionally met in hymnals, such as

In dulci jubilo, now sing with hearts aglow...

Currently I'm entering "Muscogee/English" under "language" and "Muscogee" under "Original language" for the former and "Latin/English" in both columns for the latter.
