Yes. The core narrative can stay the same across firms because your background does not change, but the reasons for that specific firm should not read like a find-and-replace exercise.

Usually the opening story, major experience, and career motivation can be reused. The customization should appear where you explain why the firm, office, or practice is a fit for you.

A strong tailored paragraph might reference a conversation, practice strength, or recruiting experience that genuinely influenced your interest rather than repeating website language.

Build one strong base letter, then customize the firm-specific section and any examples that make the fit stronger. Quality matters more than rewriting every sentence from scratch. Use one concrete example to make the point easier to believe and easier to remember. For more detail, see the consulting cover letter guide.

A base letter plus a real firm-specific paragraph seems efficient.
