Negcon Support in Mednafen PSX Core

Just a quick one: Is Negcon support on the development roadmap for the Mednafen core in Retroarch at all? I read that it was implemented in Mednafen but don’t believe it is available or ported in Retroarch. It’d be great to be able to play earlier pre-dualshock PS1 games with analog control using my Dual Shock 3 on my PC (Wipeout 1 and 2097 for example)
