You could use a delegate to pass your method's code into a single try catch like the following example:

    private void GlobalTryCatch(Action action)
    {

        {
            action.Invoke();
        }
        catch (ExpectedException1 e)
        {
            throw MyCustomException("Something bad happened", e);
        }
        catch (ExpectedException2 e)
        {
            throw MyCustomException("Something really bad happened", e);
        }
    }

    public void DoSomething()
    {
        GlobalTryCatch(() =>
        {
            // Method code goes here
        });
    }
