Beautify the output in format .po of lconvert or add some sort of argument as "switch"

When the source string and/or translated string are relatively long, they are automatically broken into multiple lines if converted to .po format. I attached a .ts file as an example. Steps to reproduce:
1. lrelease test.ts -qm test.qm
2. lconvert -i test.qm -if qm -o test.po -of po

Then the content of .po file will look like:

msgid ""
"The device '%1' reached via one click to connect (DHCP) has a different "
"Engineering ID."
msgstr ""
"Das Gerät '%1' erreichbar über DHCP (ein Klick um zu verbinden) hat eine "
"andere Engineering ID."

Some users are not very satisfied with such formatting. They'd like "one-liners", like:

msgid "The device '%1' reached via one click to connect (DHCP) has a different Engineering ID."
msgstr "Das Gerät '%1' erreichbar über DHCP (ein Klick um zu verbinden) hat eine andere Engineering ID."

Update: the result is the same if .ts file is converted directly to .po file
