In the 19th century publications, text is often centered between the last neume of a paragraph and its right-aligned martyria. While it is possible to center text within an inline text box (modulo #646), it is not currently possible to center the inline text box itself between the last neume and the right-aligned martyria. This forces the user to enter the rubrics on a brand new line using a (non-inline) text box, which can often disrupt the vertical spacing of the page.
