I often have to use some custom citation like: “(for details see: Author et al., 2017)”. OpenOffice/LibreOffice connection tool is already capable of doing similar thing but only in the end of citation like: “(Author et al., 2017; YOUR_TEXT)” when one use option “Cite special”.
It would be nice to have an option in “Cite special” to decide if “YOUR_TEXT” is added before or after citation.
