Your goal is to create a function to format a number given a template; if the number is not present, use the digits `1234567890` to fill in the spaces.

A few rules:

* the template might consist of other numbers, special characters or the like: you need to replace only alphabetical characters (both lower- and uppercase);
* if the given or default string representing the number is shorter than the template, just repeat it to fill all the spaces.

A few examples:

```python
numeric_formatter("xxx xxxxx xx","5465253289") == "546 52532 89"
numeric_formatter("xxx xxxxx xx") == "123 45678 90"
numeric_formatter("+555 aaaa bbbb", "18031978") == "+555 1803 1978"
numeric_formatter("+555 aaaa bbbb") == "+555 1234 5678"
numeric_formatter("xxxx yyyy zzzz") == "1234 5678 9012"
```
