CSV import for custom workout programs

Please add the ability to import custom workout programs from a CSV file using Speediance program parameters, so users can create and upload multiple structured programs in batch instead of building each one manually. This would make program creation much faster for advanced users, coaches, and anyone managing many custom workouts, while also reducing repetitive manual input and making custom programming more scalable. Suggested CSV fields could include: program name, workout name, exercise name, exercise type or movement type, set count, rep or time target, resistance/load mode, rest time, tempo or speed settings, notes/instructions, exercise order within each workout, and workout order within each program. Ideally, Speediance would also provide a downloadable CSV template, field validation with clear error messages, a preview before import, and support for batch import of multiple workouts inside one program as well as multiple programs in a single file. This feature would complement existing requests around custom programs, but it solves a different problem: efficient, structured input at scale, not just manual editing inside the app.
