SME V tonearm - abnormalities in alignment ?

The SME V tonearm does feature no options to align offset nor overhang in the headshell alone. The mounting holes are not oblonged and the headshell is fixed and can't be rotated at all.
How can a cartridge be aligned to different arcs (Baerwald/lofgren, Loefgran, Bauer, Stevenson et al.) ?

Just be moving the base in the SME slide-frame?

Does the SME V do allow the alignment of cartridges with specific mechnaical parameters only?

Any other way - aside from small washers - to align lateral tracking angle (lateral azimuth) ?

Is the only possible option for a perfect alignment an individual alignment tractor for a specific given cartridge - like the MINT tractor ?

Does anyone have experience with modified SME V with custom made oblonged mounting holes and/or modified to detachable headshell ?

How to align the SME V to different zero-error curves?
