How to adjust padding (if at all) underneath lyrics in SATB reductions?

[Aristotle Esguerra]

Is it possible to adjust the padding/vertical spacing between the final line of a multi-stanza hymn and the TB staff in an SATB choir reduction?

I am aware of some solutions that use hard-coded values (i.e., assuming a set number of stanzas), but as this is intended as the basis for a template for anywhere from 1–16 verses, those are unusable in this case.
