pfsDesign for DCB is overwritten if the light source of other SM is set to PFI

At present (18 Feb 2024), SM1 light source is set as PFI for lamp test, and at the same time SM3 and SM4 are set as DCB1 and DCB2 to measure new focus after thermal cycle and test Image Quality. When I ran detThroughFocus sequence for SM3 (DCB1), pfsDesign was set for Cobra Home position. (But FITS comment says "pfsDesign, from dcb").

Although it is natural to think that if one SM is connected to PFI other SMs are connected too, iic should check light source of each SM, I think.
